Pylint W0221 gives the warning
Argument number differs from overridden method.
Why is this a problem? I'm overriding the method to add additional
functionality.
There are exceptions to every guideline. Doing this could easily be a mistake,
so it's one of the many things that Pylint checks for. Silence the warning if
you like.

Thanks I was just wondering if I was overlooking something about
inheritance.
This is only my opinion but you get this warning because of 2 disctinct
issues:
1/ you just made a basic mistake in your signature and need to correct it
2/ you did not make any mistake in the signature, but this warning may
reveal a (small) flaw in your class design.
I don't know the exact context for your code, but it's better to have a
consistant interface over your methods and mask the implementation
details from the user.
In your case, the getRays method may always ask for the lambda
parameters and just ignore it for one of its implementation.
And don't write empty doctrings to trick pylint. Either write them, or
remove this rule, you are loosing all the tool benefits.
